Momentum continues to grow in development of a suite of standards that ultimately will make possible a next-generation, IP-based television transmission system.
Four additional subsystem standards, which will be part of the overall ATSC 3.0 standard, have been elevated to candidate standard status by a vote of the Advanced Television Systems Committee Technology Group 3, TG3, according to the ATSC.
The new candidate standards include A/338 for companion device second screen services; A/322, service announcement encoding and transport of metadata for Electronic Service Guide; and A/335, video watermark, and A/334. audio watermark standards, to insert metadata information into the video signal.
They join the physical layer components of the next-gen standard as candidate standards.
According to ATSC, six more subsystem standards are expected to be elevated to candidate standard status this month. They include:
- A/341 video standard
- A/331 signaling, delivery standard, synchronization and error protection standard
- A/343 captions and subtitles standard
- A/330 link layer protocol standard
- A/333 service reporting standard
- A/336 audio/video watermark payload standard
